1 r This invention relates to improvements in I springstructures, Y

N Themain objects of the invention are:

' First, to provide an improved spring structure having a top borderframe which is effective in Second, to provide a border frame for springcushion structures which may be readily constructed to any desiredoutline for the purpose of supporting upholstery or providing a cushionstructure of desired shape and at the same time one which may be readilyapplied to a spring structure.

Third, to provide a border frame for spring structures to which thebraces and cross members may be effectively connected.

Objects relating to details and economies of 6 Claims. (01. 5-250) theinvention will appear from the description to follow. The invention isdefined and pointed out in the claims.

A preferred embodiment of the invention is 2 1 members 4 and 5 areformed of suitable'gauge of rod or wire and are of round section;

V The frame members are fixedly secured or connected together by meansofthe sheet metal clips 9 and It), the clips 10 being quite similar to theclips 9 but are designed to secure the braces II to the frame members. Ii

The inner frame members 5 have loop-like offsets I2 formed therein atlongitudinally spaced intervals or in the positions at which the clipsare to be attached. a

The clips 9 have downward offsets l3 in the intermediate portionsthereof providing shoulders M which engage the inner sides of the framemembers at each side' of the offsets l2 thus preventing longitudinalmovement of the clips on the frame members' r The ends of the clips I-5and [Bare clamped around the frame -members as is illustrated therebyfixedly securing them to the frame members and fixedly securing theframe members in laterally spaced relation. The offsets 12 in the innerborder member prevent relative rotative movement of the clips and theinner frame memillustrated in the accompanying drawing, in bet which:

Fig. 1 is a fragmentary plan view of a spring structure embodyingthefeatures of the invention, the bottom frame being omitted and onlyportions of the top frame and bodysprings being In the accompanyingdrawing, the body springs 40 I are of the helical type and mounted on asuitable base including cross members 2. The base member 3 is notillustrated and only a part of the body springs are illustrated.Adjacent springs in the assembly illustrated are connected 5 by thecrossed helical tie members 3.

My improved border frame comprises an outer frame member 4 and an innerframe member 5, these frame members being disposed in spaced relationand being provided with portions 6 and 1 respectively disposed at theends of the cushions.

The top coils of the front and a portion of the end border springs aresecured to the outer frame member 4 by means of the clips 8. These frameThe clips ID are the sameas described except that they are somewhatwider and have an intermediate portion or web thereof struck out toprovide tongues I! which are clamped around the laterally disposed armsI8 of the brace or tie memberll. Y The present structure 'is'anembodiment or adaptation of' the structure of my Patent No.

2,336,9'75, "issued December 114, 194 3; 1;; that structure the framemembers are or flattened cross section. My present invention permits theuse of round stock.

The border frame is in effect a truss structure and is effective inresisting bending and wracking strains. The clips, being of substantialWidth and engaging each frame member at spaced points, are effective asstruts. The members 4 and 5 may be made of quite light gauge stock andat the same time the structure is very strong and capable of resistingstrains and stresses tending to distort the upholstery cushion.

I have illustrated and described an embodiment of the invention which ishighly practical. I have not attempted to illustrate or describe otherembodiments or adaptations as it is believed that'this disclosure willenable those skilled in the art to embody or adapt the invention as maybe desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
